2.16.14 SPRITE OSD Function
This is especially suitable for cursor and other displays as its function allows for display in any position,
regardless of the validity of block OSD displays or display positions. SPRITE font consists of 2 charac-
ters: SPRITE fonts 1 and 2. Each SPRITE font is a RAM font consisting of 32 horizontal dots ! 20 vertical
dots, 4 planes, and 4 bits of data per dot. Each plane has corresponding color palette selection bit, and
16 kinds of color palettes can be selected by the plane bit combination (three bits) for each dot. The color
palette is set in dot units according to the OSD RAM (SPRITE) contents from among the selection range.
It is possible to add arbitrary font data by software as the SPRITE fonts consist of RAM font.
The SPRITE OSD control register can control SPRITE display and dot size. The display position can
also be set independently of the block display by the SPRITE horizontal position registers and the sprite
horizontal vertical position registers. The vertical fonts 1 and 2 can be set independently. An OSD inter-
rupt request occurs at each completion of font display. The horizontal position is set in 2048 steps in
2TOSC units, and the vertical position is set in 1024 steps in 1TH units.
When SPRITE display overlaps with other OSD displays, SPRITE display is always given priority. How-
ever, the SPRITE display overlaps with the display which includes OUT2 output, OUT2 in the OSD is
output without masking.
Notes 1: The SPRITE OSD function cannot output OUT2.
2: When using SPRITE OSD, do not set HS ≤ “00316”, HS ≥ “80016.”
3: When using SPRITE OSD, do not set VSi = “00016,” VSi ≥ “40016.”
4: When displaying with SPRITE fonts 1 and 2 overlapped, the SPRITE font with a larger set value
as the vertical display start position is displayed. When the set values of the vertical display
start position are the same, the SPRITE font 1 is displayed.
